I, Willie Sutton

Willie Sutton is probably the best known bank robber in America (he was once even profiled on "60 Minutes"). Although his chosen occupation is pretty dubious, he was very good at it, and this biography is a truly gripping read. I can't give examples without spoiling the story, but it's one of the best true crime books I've read and would recommend it to anyone. Note that there's this book and "Where the Money Was" - both are very similar, so choose one or the other. Utterly engrossing.
